What is a Folded Fin Heat Sink?

A folded fin heat sink is a thermal component formed through precision stamping and folding processes. Its core feature lies in its multi-layered, high-density aluminum/copper fin structure, which significantly increases heat dissipation surface area. Combined with heat pipes or liquid cooling technology, it achieves superior thermal conductivity. Key advantages over traditional heat sinks include:

1. Lightweight Design: Aluminum-based materials reduce weight by 30%-50%.
2. High Thermal Efficiency: Fin density reaches 20-40 fins per inch, tripling heat dissipation area.
3. Flexible Customization: Supports irregular shapes for compact spaces and high-power applications.
4. Process Stability: Ensures consistency through CNC machining, welding, and stamping.

Why Choose IGS Folded Fin Heat Sinks?

1. Technical Expertise:
   • Optimized fin layouts based on liquid cooling simulations (e.g., 2.32°C temperature difference for 300W servers) ensure thermal resistance ≤0.026°C/W.
   • Integration of sintered heat pipe technology (dual/single-sided sintering) and liquid-cooled brazing enhances thermal efficiency.
2. End-to-End Quality Control:
   • Certified under ISO9001/14001/45000 systems, supported by ROHS analyzers, 3D measuring instruments, and a 40-member QC team (CQE/SQE/PQE).
3. Scalable Production:
   • Monthly capacities: 400K stamped parts, 650K CNC-machined components, and 5M heat pipes for rapid prototyping and bulk orders.
4. Cost Efficiency:
   • Utilizes friction stir welding (low-cost for large parts) and tube pressing (for laser/motor applications) to balance performance and budget.
